-faasd is [OpenFaaS](https://github.com/openfaas/) reimagined, but without the cost and complexity of Kubernetes. It runs on a single host with very modest requirements, making it very fast and easy to manage. Under the hood it uses [containerd](https://containerd.io/) and [Container Networking Interface (CNI)](https://github.com/containernetworking/cni) along with the same core OpenFaaS components from the main project.

Under the hood it uses [containerd](https://containerd.io/) and [Container Networking Interface (CNI)](https://github.com/containernetworking/cni) along with the same core OpenFaaS components from the main project.
 
-## When should you use faasd over OpenFaaS on Kubernetes?
+![faasd logo](docs/media/social.png)
 
-* You have a cost sensitive project - run faasd on a 5-10 USD VPS or on your Raspberry Pi
-* When you just need a few functions or microservices, without the cost of a cluster
-* When you don't have the bandwidth to learn or manage Kubernetes
-* To deploy embedded apps in IoT and edge use-cases
-* To shrink-wrap applications for use with a customer or client
+## Use-cases and tutorials
 
-faasd does not create the same maintenance burden you'll find with maintaining, upgrading, and securing a Kubernetes cluster. You can deploy it and walk away, in the worst case, just deploy a new VM and deploy your functions again.
+faasd is just another way to run OpenFaaS, so many things you read in the docs or in blog posts will work the same way.

+### About faasd
+
+* faasd is a static Golang binary
 * uses the same core components and ecosystem of OpenFaaS
+* uses containerd for its runtime and CNI for networking
 * is multi-arch, so works on Intel `x86_64` and ARM out the box
-* can be set-up and left alone to run your applications
+* can run almost any other stateful container through its `docker-compose.yaml` file
 
-![demo](https://pbs.twimg.com/media/EPNQz00W4AEwDxM?format=jpg&name=small)
+Most importantly, it's easy to manage so you can set it up and leave it alone to run your functions.

-### A note on private repos / registries
-
-To use private image repos, `~/.docker/config.json` needs to be copied to `/var/lib/faasd/.docker/config.json`.
-
-If you'd like to set up your own private registry, [see this tutorial](https://blog.alexellis.io/get-a-tls-enabled-docker-registry-in-5-minutes/).
-
-Beware that running `docker login` on MacOS and Windows may create an empty file with your credentials stored in the system helper.
-
-Alternatively, use you can use the `registry-login` command from the OpenFaaS Cloud bootstrap tool (ofc-bootstrap):
-
-```bash
-curl -sLSf https://raw.githubusercontent.com/openfaas-incubator/ofc-bootstrap/master/get.sh | sudo sh
-
-ofc-bootstrap registry-login --username <your-registry-username> --password-stdin
-# (the enter your password and hit return)
-```
-The file will be created in `./credentials/`
-
-### Logs for functions
-
-You can view the logs of functions using `journalctl`:
-
-```bash
-journalctl -t openfaas-fn:FUNCTION_NAME
-
-
-faas-cli store deploy figlet
-journalctl -t openfaas-fn:figlet -f &
-echo logs | faas-cli invoke figlet

+## Learning faasd
 
-The [OpenFaaS docs](https://docs.openfaas.com/) provide a wealth of information and are kept up to date with new features.
+The faasd project is MIT licensed and open source, and you will find some documentation, blog posts and videos for free.
+
+However, "Serverless For Everyone Else" is the official handbook and was written to contribute funds towards the upkeep and maintenance of the project.

+
+You'll learn how to deploy code in any language, lift and shift Dockerfiles, run requests in queues, write background jobs and to integrate with databases. faasd packages the same code as OpenFaaS, so you get built-in metrics for your HTTP endpoints, a user-friendly CLI, pre-packaged functions and templates from the store and a UI.
+
+Topics include:
+
+* Should you deploy to a VPS or Raspberry Pi?
+* Deploying your server with bash, cloud-init or terraform
+* Using a private container registry
+* Finding functions in the store
+* Building your first function with Node.js
+* Using environment variables for configuration
+* Using secrets from functions, and enabling authentication tokens
+* Customising templates
+* Monitoring your functions with Grafana and Prometheus
+* Scheduling invocations and background jobs
+* Tuning timeouts, parallelism, running tasks in the background
+* Adding TLS to faasd and custom domains for functions
+* Self-hosting on your Raspberry Pi
+* Adding a database for storage with InfluxDB and Postgresql
+* Troubleshooting and logs
+* CI/CD with GitHub Actions and multi-arch
+* Taking things further, community and case-studies

+
+### Deploy faasd
+
+The easiest way to deploy faasd is with cloud-init, we give several examples below, and post IaaS platforms will accept "user-data" pasted into their UI, or via their API.
+
+For trying it out on MacOS or Windows, we recommend using [multipass](https://multipass.run) to run faasd in a VM.
+
+If you don't use cloud-init, or have already created your Linux server you can use the installation script as per below:
+
+```bash
+git clone https://github.com/openfaas/faasd --depth=1
+cd faasd
+
+./hack/install.sh
+```
+
+> This approach also works for Raspberry Pi
+
+It's recommended that you do not install Docker on the same host as faasd, since 1) they may both use different versions of containerd and 2) docker's networking rules can disrupt faasd's networking. When using faasd - make your faasd server a faasd server, and build container image on your laptop or in a CI pipeline.

-### Supported operations
+For completed features, WIP and upcoming roadmap see:
 
-* `faas login`
-* `faas up`
-* `faas list`
-* `faas describe`
-* `faas deploy --update=true --replace=false`
-* `faas invoke --async`
-* `faas invoke`

-* `faas version`
-* `faas namespace`
-* `faas secret`
-* `faas logs`
+See [ROADMAP.md](docs/ROADMAP.md)
 
-Scale from and to zero is also supported. On a Dell XPS with a small, pre-pulled image unpausing an existing task took 0.19s and starting a task for a killed function took 0.39s. There may be further optimizations to be gained.
-
-Other operations are pending development in the provider such as:
-
-* `faas auth` - supported for Basic Authentication, but OAuth2 & OIDC require a patch
-
-### Backlog
-
-* [ ] [Store and retrieve annotations in function spec](https://github.com/openfaas/faasd/pull/86) - in progress
-* [ ] Offer live rolling-updates, with zero downtime - requires moving to IDs vs. names for function containers
-* [ ] An installer for faasd and dependencies - runc, containerd
-* [ ] Monitor and restart any of the core components at runtime if the container stops
-* [ ] Provide ufw rules / example for blocking access to everything but a reverse proxy to the gateway container
-* [ ] Provide [simple Caddyfile example](https://blog.alexellis.io/https-inlets-local-endpoints/) in the README showing how to expose the faasd proxy on port 80/443 with TLS
-
-### Known-issues
-
-* [ ] [containerd can't pull image from Github Docker Package Registry](https://github.com/containerd/containerd/issues/3291)
-
-### Completed
-
-* [x] Provide a cloud-init configuration for faasd bootstrap
-* [x] Configure core services from a docker-compose.yaml file
-* [x] Store and fetch logs from the journal
-* [x] Add support for using container images in third-party public registries
-* [x] Add support for using container images in private third-party registries
-* [x] Provide a cloud-config.txt file for automated deployments of `faasd`
-* [x] Inject / manage IPs between core components for service to service communication - i.e. so Prometheus can scrape the OpenFaaS gateway - done via `/etc/hosts` mount
-* [x] Add queue-worker and NATS
-* [x] Create faasd.service and faasd-provider.service
-* [x] Self-install / create systemd service via `faasd install`
-* [x] Restart containers upon restart of faasd
-* [x] Clear / remove containers and tasks with SIGTERM / SIGINT
-* [x] Determine armhf/arm64 containers to run for gateway
-* [x] Configure `basic_auth` to protect the OpenFaaS gateway and faasd-provider HTTP API
-* [x] Setup custom working directory for faasd `/var/lib/faasd/`
-* [x] Use CNI to create network namespaces and adapters

+## Instructions for testing a patch for faasd
+
+### Launch a virtual machine
+
+You can use any kind of Linux virtual machine, Ubuntu 20.04 is recommended.
+
+Launch a cloud VM or use [Multipass](https://multipass.run), which is free to use an can be run locally. A Raspberry Pi 3 or 4 could also be used, but will need you to run `make dist` to cross compile a valid binary.
+
+### Copy over your SSH key
+
+Your SSH key will be used, so that you can copy a new faasd binary over to the host.
+
+```bash
+multipass launch \
+  --mem 4G \
+  -c 2 \
+  -n faasd
+
+# Then access its shell
+multipass shell faasd
+
+# Edit .ssh/authorized_keys
+
+# Add .ssh/id_rsa.pub from your host and save the file
+```
+
+### Install faasd on the VM
+
+You start off with the upstream version of faasd on the host, then add the new version over the top later on.
+
+```bash
+cd /tmp/
+git clone https://github.com/openfaas/faasd --depth=1
+cd faasd/hack
+./install.sh
+
+# Run the login command given to you at the end of the script
+```
+
+Get the multipass IP address:
+
+```bash
+export IP=$(multipass info faasd --format json| jq -r '.info.faasd.ipv4[0]')
+```
+
+### Build a new faasd binary with the patch
+
+Check out faasd on your local computer
+
+```bash
+git clone https://github.com/openfaas/faasd
+cd faasd
+
+gh pr checkout #PR_NUMBER_HERE
+
+GOOS=linux go build
+
+# You can also run "make dist" which is slower, but includes
+# a version and binaries for other platforms such as the Raspberry Pi
+```
+
+### Copy it over to the VM
+
+Now build a new faasd binary and copy it to the VM:
+
+```bash
+scp faasd ubuntu@$IP:~/
+```
+
+Now deploy the new version on the VM:
+
+```bash
+killall -9 faasd-linux; killall -9 faasd-linux ; mv ./faasd-linux /usr/local/bin/faasd
+```
+
+### Check it worked and test that patch
+
+Now run a command with `faas-cli` such as:
+
+* `faas-cli list`
+* `faas-cli version`
+
+See the testing instructions on the PR and run through those steps.
+
+Post your results on GitHub to assist the creator of the pull request.
+
+You can see how to get the logs for various components using the [eBook Serverless For Everyone Else](https://gumroad.com/l/serverless-for-everyone-else), or by consulting the [DEV.md](/docs/DEV.md) guide.

+* `faas store list/deploy/inspect`
+* `faas version`
+* `faas namespace`
+* `faas secret`
+* `faas logs`
+* `faas auth` - supported for Basic Authentication and OpenFaaS PRO with OIDC and Single-sign On.
+
+Scale from and to zero is also supported. On a Dell XPS with a small, pre-pulled image unpausing an existing task took 0.19s and starting a task for a killed function took 0.39s. There may be further optimizations to be gained.
+
+## Constraints vs OpenFaaS on Kubernetes
+
+faasd suits certain use-cases as mentioned in the README file, for those who want a solution which can scale out horizontally with minimum effort, Kubernetes or K3s is a valid option.
+
+### One replica per function
+
+Functions only support one replica, so cannot scale horizontally, but can scale vertically.
+
+Workaround: deploy one uniquely named function per replica.
+
+### Scale from zero may give a non-200
+
+When scaling from zero there is no health check implemented, so the request may arrive before your HTTP server is ready to serve a request, and therefore give a non-200 code.
+
+Workaround: Do not scale to zero, or have your client retry HTTP calls.
+
+### No clustering is available
+
+No clustering is available in faasd, however you can still apply fault-tolerance and high availability techniques.
+
+Workaround: deploy multiple faasd instances and use a hardware or software load-balancer. Take regular VM/host snapshots or backups.
+
+### No rolling updates
+
+When running `faas-cli deploy`, your old function is removed before the new one is started. This may cause a small amount of downtime, depending on the timeouts and grace periods you set.
+
+Workaround: deploy uniquely named functions per version, and switch an Ingress or Reverse Proxy record to point at a new version once it is ready.
+
+## Known issues
+
+### Non 200 HTTP status from the gateway upon first use
+
+This issue appears to happen sporadically and only for some users.
+
+If you get a non 200 HTTP code from the gateway, or caddy after installing faasd, check the logs of faasd:
+
+```bash
+sudo journalctl -u faasd
+```
+
+If you see the following error:
+
+```
+unable to dial to 10.62.0.5:8080, error: dial tcp 10.62.0.5:8080: connect: no route to host
+```
+
+Restart the faasd service with:
+
+```bash
+sudo systemctl restart faasd
+```
+
+## Backlog
+
+Should have:
+
+* [ ] Offer a recommendation or implement a strategy for faasd replication/HA
+* [ ] Monitor and restart any of the core components at runtime if the container stops
+* [ ] Asynchronous function deletion instead of synchronous
+* [ ] Asynchronous function start-up instead of synchronous
+
+Nice to Have:
+
+* [ ] Terraform for AWS (in-progress)
+* [ ] Total memory limits - if a node has 1GB of RAM, don't allow more than 1000MB of RAM to be reserved via limits
+* [ ] Offer live rolling-updates, with zero downtime - requires moving to IDs vs. names for function containers
+* [ ] Multiple replicas per function
+
+### Completed
+
+* [x] Docs or examples on how to use the various event connectors (Yes in the eBook)
+* [x] Resolve core services from functions by populating/sharing `/etc/hosts` between `faasd` and `faasd-provider`
+* [x] Provide a cloud-init configuration for faasd bootstrap
+* [x] Configure core services from a docker-compose.yaml file
+* [x] Store and fetch logs from the journal
+* [x] Add support for using container images in third-party public registries
+* [x] Add support for using container images in private third-party registries
+* [x] Provide a cloud-config.txt file for automated deployments of `faasd`
+* [x] Inject / manage IPs between core components for service to service communication - i.e. so Prometheus can scrape the OpenFaaS gateway - done via `/etc/hosts` mount
+* [x] Add queue-worker and NATS
+* [x] Create faasd.service and faasd-provider.service
+* [x] Self-install / create systemd service via `faasd install`
+* [x] Restart containers upon restart of faasd
+* [x] Clear / remove containers and tasks with SIGTERM / SIGINT
+* [x] Determine armhf/arm64 containers to run for gateway
+* [x] Configure `basic_auth` to protect the OpenFaaS gateway and faasd-provider HTTP API
+* [x] Setup custom working directory for faasd `/var/lib/faasd/`
+* [x] Use CNI to create network namespaces and adapters
+* [x] Optionally expose core services from the docker-compose.yaml file, locally or to all adapters.
+* [x] ~~[containerd can't pull image from Github Docker Package Registry](https://github.com/containerd/containerd/issues/3291)~~ ghcr.io support
+* [x] Provide [simple Caddyfile example](https://blog.alexellis.io/https-inlets-local-endpoints/) in the README showing how to expose the faasd proxy on port 80/443 with TLS
+* [x] Annotation support
+* [x] Hard memory limits for functions
+* [x] Terraform for DigitalOcean
+* [x] [Store and retrieve annotations in function spec](https://github.com/openfaas/faasd/pull/86) - in progress
+* [x] An installer for faasd and dependencies - runc, containerd
